Allen Beadlay load balancer
(OP)
Came across an Allen Bradley 509 motor starter component the other day and was interested to find out its'use. It was in the parts cabinet with verbage "load balancer" imprinted on it. Looked somewhat like an aux contact w/o the contact!

Power Pole Adders — The 1 N.O. and 1 N.C. power poles may be field added to all size 0…4 Bulletin 500 line contactors and starters except the Bulletin 500L and 500FL. Two- and three-pole contactors will accept a maximum of two adder poles and four-pole devices will accept one adder pole. Each adder pole kit includes a mechanical load balancer to be used when only one power pole is added.
With the addition of one power pole to the side of a contactor the mechanism will be subject to a lot of side force, wearing and possible jamming. A mechanical load balancer is added to the other side of the contactor to provide an offsetting, balancing mechanical load so that the side forces are minimized.

Don't worry Jeff. I may be well ahead of you in the number of typos I make.
